A support tool for working time bargaining by considering individual time accounts and annual leave
(2010-01-01)
Article
Accés restringit per política de l'editorialWorking time accounts (WTAs) are employer-oriented flexibility systems that have been applied in industry but could be used far more. Their use is limited by the complexity of planning them, assessing their financial ... -
A unit cost adjusting heuristic algorithm for the integrated planning and scheduling of a two-stage supply chain
(OmniaScience, 2014-12)
Article
Accés obertPurpose: The stable relationship of one-supplier-one-customer is replaced by a dynamic relationship of multi-supplier-multi-customer in current market gradually, and efficient scheduling techniques are important tools ... -
